I rode on an A319 on 12/25 (ATL-MSY) that had already been updated with EC. Sorry, no pictures, but I will say the leg room improvement didn't look like much. It certainly was not as much as the exit room leg room, but I would rather have had an EC window seat that the odd arm rest of the window exit row seat.

Anyone know of any thread or website tracking the progress of the fleet conversion to EC?
